Bjorn3D posted a review on the Enermax Galaxy 850W Power Supply

Many power supply companies have been offering high-end power supply that can deliver tremendous amount of wattage all the way up to 1kWs (we had a review on the PC Power & Cooling). What sets this power supply aparts from the others? Well, Enermax claims that their power supply is the first in the industry that has “five 12V rails (while others in the industry only has 4), which are an integral part of the upcoming revision of EPS12V PSU design guided by Intel”. Not only that it has 5 rails, they are versatile enough to power “Quad Core & Quad CPU system as well as Quad graphics systems” (Triple Quad as Enermax calls it) simultaneously. In addition, Enermax emphasizes that this power supply is fully rated at 50°C. Since power supply loses its delivery capacity as the operating temperature increased, by testing the power supply at 50°C, Enermax guarantees that the PSU will deliver the rated wattage at 50C, which is the temperature at which most computers operate at or below. Okay, enough of what Enermax says, let’s see what is packed in this baby.
